7 '0 all whom it may concern:

Be it known that I, RALPH W. NnwooMB, a citizen of the United States residing at Green Village, in the county of Morris and State of New Jersey, have invented a certain new and useful'lmprovement in Devices for Controlling Rotary Motion of Shafts, Eta, of which the following is a specification.

The invention is a device for controlling rotary motion of a shaft, spindle or .other rotatable member, whereby said member may be caused to rotate in-either direction in order to operate a valve or for any other purpose at the will of the operator. lit is susceptible to. a large variet of applications, such as the regulation 0 temperature,

pressure, liquid flow, mechanical motion,

furnace rheostats and dampers, the mixing of gases in fixed ratio to one another, and the operation of valves from a distant point. The invention consists in the construction more particularly hereinafter set forth.

In the accompan ing drawings Fig. 1 is a side e evation of my regulator. Fig. 2 is anend elevation. Figs. 3 and 4 are similar enlarged side elevations of the upper portion of the device, showing the positions of the yoke plate and actuating plunger armatures when different pawls are in engagement with the ratchet. Fig. 5 is an enlarged face view of the device for varying the amplitude of vibration of the lever 12.

Similar letters of reference indicate like parts.

My regulator is here shown applied to controlling a faucet valve 2 inpipe 3. On the valve shaft is a sprocket 4 which by sprocket chain 5 receives motion from a sprocket 6 on the shaft 7. Said shaftis supported in a sleeve 8 upon an upright secured upon cross bar 9 which extends between the side walls 1001? the machine bed 11, Fig. 2.

Supported upon shaft 7 and swinging thereon is a lever 12 having a long slot 13 which receives a stud 14: on the face of sector plate 15. Said plate is pivoted at 16 to the face of a disk 17 which is ,fast on one end of shaft 18. Shaft 18 is journaled in the side walls 10 of the bed 11 and between said walls carries a pinion 19, with Which engages the worm 20 on the shaft 21 of an electric motor 22 which is supported on bed 11. In the sector late 15 is an arc-shaped slot 23, in which. ot is a clamping pin 24 entering disk17, Fig. 5. B moving the sector plate 15 on its pivot, t e distance of the stud from the centerof disk 17 may be varied, and in this way I'may adjust the amplitude of vibration of the lever 12. Fast upon the lever 12 is a plate carrying two upright solenoids 25 and 26. The

plunger [armatures 27 of said solenoids at their lower ends are provided with rods 28,

on which are helical retracting springs 29. On the u horizontal y slotted plates 30. The slots in plates 30receive pins 31 on a yoke plate 32 plvoted at its middle portion to lever 12. Also on said plate are pivoted two pawls 33, 34. .The lower sides of said pawls bear against the arms of a leaf spring 35 which is secured at its middle portion to said, yoke plate by a pin 36. The upper sides of said pawls bear against stops 37 on yoke plate 32. The pawls 33, 34: are in cooperative relation to a ratchet wheel 38 on shaft 7.

The coils of solenoids 25, 26 are in paral lel with a batter 39, Figs. 3 and 4, which may be connecte in circuit with either solenoid, or be out out altogether by switch 40.-

per ends of said armatures are at Q springs 29 oppose one another and hold the yoke plate 32 in a neutral position when neither solenoid is energized, at which time both of the pawls 33, 34 are out of engagement with ratchet wheel 38. and are held up against their stops by spring 35.

When the switch 40 is set to close circuit to solenoid 25, said oke plate is tilted as shown in Fig. 3, so t at the pawl 34 comes into engagement with ratchet wheel 38, and can operate to rotate said wheel in the direction of the arrow a. When the switch 40 is set to 'close circuit to solenoid 26, said yoke plate is tilted as shown inFig. 4, so that the awl 33 comes into engagement with rate et wheel 38, and can operate to rotate said wheel in the opposite directionthat is to say, in thedirection of arrow 6. And in either-case the operation takes place during one half of each revolution of stud 14.

I claim:

1. A device for controlling rotary mo-, tion comprising a motor, avibrating lever actuated by said motor, a shaft, transmitwe I ting mechanism for converting the vibrat- "means for electrically controlling the direc-' bratory ing movement of said Ieverinto rotary mo o erating with said ratchet wheel, and fixed e ectromagnetic means on said lever for tilting said yoke to bring either of said paw'ls into engagement with said ratchet.

2. A device for controlling rotary inc- 3 tion, comprising a motor, a shaft rotated 15 second shaft, a swinging lever, a pivoted yoke plate on said lever, a ratchet wheel on said second shaft, a pawl on said yoke plate cooperating with said ratchet thereby, a

wheel, and a solenoid fixed on saidlever and controlling the tilting of said yoke plate thereon to cause engagement of said pawl actuate said sec= and'said ratchet wheel to end shaft.
